摘要:The invention offers the ability to rapidly synthesize multiple chemical compounds, particularly polymers of varying sequences, in parallel on the surfaces of carrier beads. Tinvention involves attaching up-converting phosphors (UCP's) to beads to create up-converting phosphor-loaded beads (UCP-loaded beads) with unique spectral characteristics. Using a dynamic sorting architecture each bead is cataloged based on its spectral characteristics, assigned a compound or polymer to be synthesized, and subjected to multiple rounds of sorting by a flow cytometer, wherein each round sorts the bead to an appropriate bin for a selected chemical reaction, such as the attachment of a monomeric subunit of the polymer sequence.

标 题:Rare earth downconverting phosphor compositions for optically encoding objects and methods and apparatus relating to same

摘要:A rare earth (RE) downconverting phosphor composition may contain two or more lanthanide materials each having a host and at least one downconverting emitter. Each lanthanide material emits a detectable electromagnetic radiation emission peak at an intensity, which is proportional to the amount of emitter present, upon excitation with an absorbable electromagnetic radiation, the emitted radiation having a lower energy, i.e., a longer wavelength than the absorbable radiation. One or more ratios of the intensities of the emitted detectable electromagnetic radiation may be used to uniquely identify the composition. Alternatively, the RE downconverting phosphor composition may contain a lanthanide material having a host and at least two emitters. The lanthanide material emits at least two different detectable electromagnetic radiation emission peaks each at an intensity upon excitation with an absorbable electromagnetic radiation, the emitted radiation having a lower energy, i.e., a longer wavelength than the absorbable radiation.

发明人：HAUSHALTER ROBERT C
权利人:PARALLEL SYNTHESIS TECH
摘要:The present invention relates generally to encoding samples. More specifically, it relates to barcodes and compositions involving upconverters and methods including them. In a composition aspect of the invention, a composition comprising two or more lanthanide materials is provided. Each lanthanide material comprises a host, an absorber, and an emitter, and the materials emit detectable electromagnetic radiation upon excitation with absorbable electromagnetic energy. One or more relative ratios of emission intensities uniquely identify the composition.
